Title: Method and apparatus for depositing a textile fibre sliver in a can
Inventor: HOESEL FRITZ
IPC: B65H54/78
Filed: 1995-08-09
Abstract: Fibre sliver is conveyed by press rollers (16a, 16b) and is introduced in a coiled configuration into a can (19) moved beneath a rotary delivery head (17), whose rotary movement is controlled by control means (43). In order to allow the sliver end to be deposited at a predetermined place in the can, the rotary movement of the delivery head is stopped at a predetermined position and the press rollers continue to convey fibre material, during which operation the can is moved. The movement of the head may also be stopped in dependence on the detected position of the can. In another embodiment where the rollers (16a, 16b), delivery head (17) and can (19) have a common drive, the control means (43) actuates a clutch in the drive train to the rotary head (17). <IMAGE>

Title: Hydraulic rotary actuator
Inventor: TONSOR ANDREW J
IPC: F15B15/12
Filed: 1995-09-20
Abstract: A hydraulically powered rotary actuator (32) for rotating a first portion (14) of a work machine (10) relative to a second portion (12) of the work machine (10) has inner and outer rings (36, 96, 38, 98) enclosed by first and second cover plates (42, 104, 44, 106). The inner and outer rings (36, 96, 38, 98) are spaced apart to define a hydraulic power chamber (56, 98) to which pressurized fluid is supplied to rotate one of the inner or outer rings (36, 96, 38, 98). The first portion (14) of the work machine (10) is connected to the rotatable ring (36, 96) and rotates with it. A large diameter bearing assembly (40, 110) rotatably supports the rotatable ring (36, 96) and the first portion (14) of the work machine (10). Most prior work machines with rotatable car or upper structure require large expensive components including gear reduction assemblies, a hydraulic motor, and large diameter swing gear. The subject actuator simplifies the construction by eliminating many of the prior components.

Patent GB-2325962-A (GB)
Title: Vehicle anti-theft security fuel lock
Inventor: PEARCE MICHAEL
IPC: B60R25/042
Filed: 1997-06-04
Abstract: A solenoid valve D is fitted in the fuel line from the fuel tank E to the engine A to be protected. When the solenoid valve D is operated it will interrupt the supply of fuel to the engine A so that the engine starts but then stalls with no indication of the reason. The closer the valve is to the engine, the quicker the engine will stall. The solenoid valve D can be controlled via several combinations of control circuits and can be used as in independent fuel immobiliser or as part of an alarm system. A manual valve may be used instead of the solenoid valve (fig.2).

Title: Adding alloying additives to an aluminothermically produced weld
Inventor: MULDER GERHARDUS JOHANNES
IPC: B22D19/02
Filed: 1997-09-12
Abstract: A process for aluminothermically welding the ends of two rails together to produce a weld with alloying additives 9 added only to the steel 5 in the region of the head of the weld by completing the aluminothermic reaction, tapping the crucible 1 and combining the alloying additives 9 to the steel 5 that will form the head of the weld as the steel 5 flows from the crucible 1 and before it runs into the casting cavity. Combination of the alloying additives 9 with the steel 5 may be achieved by forming the crucible plug 7-9 from a sand and alloying additive mixture or by placing the alloying additives 9 in a cavity on the underside of the crucible plug 7-9. As a consequence of the process a weld is formed with an alloyed, hard and wear resistant head and a ductile foot.

Title: Nozzle assembly for a rotary drill bit
Inventor: TAYLOR STEVE
IPC: B05B15/65
Filed: 1998-03-02
Abstract: A nozzle assembly for a rotary drill bit comprising a nozzle (24) for retention in a socket (25), wherein the nozzle (24) is characterised by projections (30) which are engagable with open-ended recesses (31) in a side wall of the socket (25). Once the nozzle (24) has been received in the socket (25), locking elements such as grub screws (36, fig. 5), may be engaged within inlet portions (32) of the recesses (31) in order to retain the projections (30) in the recesses (31). Further retention recesses may be provided transversely from the open-ended recesses, into which the projections may be urged. Resilient means located between the projections and the walls of the recesses, then urge the projections against the walls to retain them in place. This arrangement provides a nozzle (24) whose overall diameter is not significantly larger than the nozzle aperture itself, for example, the maximum outer cross-dimension of the nozzle may be no greater than 70% larger than the cross-dimension of the nozzle aperture. This enables the nozzle assembly to be employed in situations where space is limited. A rotary drill bit may be provided with a nozzle assembly characterised by a maximum cross-dimension and a smaller minimum cross-dimension, the nozzle assembly being orientated so that the maximum cross-dimension is generally aligned with the length of at least one blade.

Title: I.c. engine exhaust system with cooled temporary storage reservoir
Inventor: MA THOMAS TSOI HEI
IPC: F02D9/04
Filed: 1998-03-25
Abstract: The system includes a downpipe 54, at least one branch leading from an individual exhaust port 16 of the engine to the downpipe and a cooled gas storage reservoir 40 also connected to the exhaust port. The size of the reservoir 40 and the connection between the reservoir 40 and the exhaust port 16 are such as to catch and to store in the reservoir 40 the major proportion of exhaust gases discharged from the exhaust port 16 during the blowdown phase of each exhaust period when the associated exhaust valve 18 first opens. Exhaust gases in the reservoir 40 are cooled by a heat exchanger, eg, and returned to the downpipe 54 later in the engine cycle. In fig.1 the reservoir 40 comprises a plenum chamber 42 which is common to all the cylinders and which is cooled by a jacket 44 through which passes engine coolant. Exhaust gases which pass flap valve 46 enter the plenum chamber 42 and exit via the flap valve 46 and connecting pipes 36 of other cylinders with closed exhaust valves. In a modification (fig.3), each cylinder has its own storage chamber (43) and flap valves are not needed. The system prevents overheating of the catalytic converter 52 when the engine operates at fall load without requiring an external control system.
